Sugar can be addictive, wielding power over the brains of lab animals much like a craving for drugs, according to Princeton University scientists who say their findings may eventually have implications for the treatment of humans with eating disorders.
The researchers encouraged sugar binging by denying the rats food for four hours after waking. "It's a little bit like missing breakfast," Hoebel said. "As a result, they quickly eat some chow and drink a lot of sugar water."
Previous research showed hungry rats that binge on sugar experience a surge of dopamine in their brains. Dopamine is a neurotransmitter that plays a major role in addiction and affects movement, emotional response and the ability to experience pleasure and pain.
